how to add a column to include pictures

okay guys please visit this site so you would understand what I want to talk about here. what I want to do is to add a column right next to my forum list and before the buddypress default theme sidebar. and I want to include pictures inside that column is there a way to do this? now this might sacrifice some of the width with forum list column but that is fine that’s actually what I need. because I want to add some excitement to the site instead of just a white page with a forum. basically I need web design help please any ideas is welcome.
